To all whom t may concern:

Be it known that I, JOSEPH OBERMAN, Jr., a citizen of the United States,residing at Granville, in the county of'Sioux and State of Iowa, haveinvented certain new and useful Improvements in Valve Mechanism forPumps, of which the following is av specification,

This application is a division of an application filed by me December11, 1922, Serial No. 606,108.`

The invention relates to multiple delivery pumps and has for its objectthe provision of a novel valve mechanism whereby the course of the watermayv be controlled so that it 'may be delivered at the' well or causedto flow to a distant point. The invention consists in certain novelfeatures which kwill be 'hereinafter first fully described and then moreparticularly pointed out in the appended claims.

In the annexed drawing:

Figure 1 is a vertical section of a portion of a pump showing my presentinvention;

Fig. 2 is a side elevation of the spout and contiguous parts, and

Fig. 3 is a plan view. .i

In the drawing, 2 indicates a portion of the well curb and 3 indicates aportion of a base secured on the curb and having a guiding andsupporting sleeve 8 cast there- 13 denotes a bridge piece which islocated in the well and supported from the curb, said bridge piececontaining an inlet and passages through which the water flows when theoperating mechanism is actuated. Inasmuch as the particular form of theinlet and the operating mechanism are not part of the present invention,they are omitted from the drawing. A passage 87 extends through thebridge piece laterally from the inlet port to the end of the bridgepiece and one outlet for the water is arranged in the top of the bridgepiece over the end of the said passage 87 and another outlet is providedin the bottom of the bridge piece in axial alinement with therst-mentioned outlet. A packing cup 88 is secured upon the bridge pieceover the said end of the passage 87 and a delivery tube 89 has its lowerend disposed within the said packing cup. This delivery tube isconstructed of two axially alined sections threaded into the upper andlower ends,

. reepeetxely 4or a coupling head.. 90 tting within the sleeve 8, asshown. The sleeve 8 is constructed with a helical slot 91 Land the head90 is equipped with a stud 92 playing in the said slot. Rotation of thehead will cause it to ride upwardly in thesleeve when filed August lremoval of the delivery tube is desirable` for repairing or otherpurposes, and a roller may be fitted upon the stud 92 to reducefrictional wear upon thewalls ofthe slot 91. Cotter pins 93 secure thehead 90 against movement within the sleeve 8, it being .noted that thecoupling 90 is provided with an internal enlargement 900 to receive acotter pin, and is further provided kwith a recess 901 at a pointdiametrically opposite the enlargement so` that the crosssectional areaof thelbore will not be reduced to restrict the flow of the water. Theprovision of the enlargement 900 also prevents leakage around thelocking pins .or keys. Upon the lower end yof the delivery y tube 89 isfitted a packing ring or diaphragm 94 which may engage an internalshoulder 95 on the packing cup 88, and this packing ring is clamped to ashoulder 96 upon the tube 89 'by a cage or sleeve 97 which is threadedonto the lower end of the tube 89 and is provided internally with aspider 98 constituting a guide for the valve stem 99. The lower end ofthe 'sleeve 97 forms the upper outlet and is preferably beveled orflared, as shown at 100, so that it will constitute a seat for the valve101 which may conveniently be a rubber ball secured upon the stem 99 bynuts 102 disposed above and below the ball, as clearly shown. Uponreference to Fig. 1, it will be noted that the valve 101 may engage theseat 100 or may engage the seat 103 which is below the valve and definesthe lower outlet. The position of the valve is determined by verticallyadjusting the stem 99 so that the water may be directed into and throughthe delivery tube 89 or may be directed through the outy let 103 to andinto the underground service pipe. Upon the upper end of thedeliverytube 89, I secure a spout 104i through which the water may bedischarged. The stem 99 extends through the top portion of the spout andsaid top portion is constructed to receive a packing nut 105 adapted tobe turned home against packing 106 so that the said packing will becompressed about the stem 99 and leakage of the water prevented. TheStem extends threugh the 11.11@ 10.5 and @beve moutlino the Well, thehand Wheel 111 is :turned so that the valve stem 99, Wfl-1l he the sameis provided with the threaded enlargement 107, the extreme upper end ofthe stem being angularin cross: section, as,

sustaining and guiding headf-109 is secured upon the spout and projectsupwardly therefrom and is provided with the lateral lugs 'or branches1,10through which the Ythreadud and angular portion of the valve stempasses. Between the lugs 110,l a hand Wheel 111 is mounted andthis handWheel is constructed with an internally threaded'V hub engaging thethreaded portion 107 of"l the valve steinI so that rotation of the handWheel Will effect vertical movement the and consequentlyl adjust theval-ve 101, as clesrled-A IntheA under side of the'brid-ge pieee is argroove 112 which forms the upper portion of; a lateral; passageextending'frorn the 'porti' ofthe.y valve seat`103l to the mentionedundergroundrservice pipe. A flange` 115 is securedvto the under sideofthe bridge piece and' this'flange is provided in its/upperside with agroove or recess 116mating with the V groove'112 to complete the passageto the underground service pipe.

W hen. the Water is to be delivered` at the driven downwardly and thevalveA 101 caused toengage the seat 103. The flow of Water throughthepassage provided by the grooves 11.2 and 116 to the undergroundservice connection will;v be thereby prevented and the Water Will risethrough the delivery tube 89 toi the spout- 104. Ii the valve be caused.to engage. the seat 100, the flow of Water through the delivery tube 89will be prevented and it will flo-e7V through the port 103 andv thepassage leadingtherefrom to the underground service, pipe, as will beread-ily understood.

Having thus described the inventiongvhat isy claimed as new is:

In a pump, the combination ofl vertically disposed delivery tube, adelivery. spout at the upperH end ofi said tube, aI valve adapted. toseat against the lower end of said tube, a valve stem extending; throughthe said' tube and carryingthefsaid valve, a bracket securedl upon andrising from` the spout and' having spaced lateral members above` thedeliveryy tube, the valve-stem having a threaded portion extendingloosely through the said spaced members, and a hand Wheel mounted uponysaid threaded portion ofi the v valve` stem between said spaced members.
